Case 1 (Questions 11-13) Suppose a team of researchers conducts a case-control study on the association between hypertension and stroke among adults aged 50 and older in Florida. For this study, the researchers selected Floridian adults aged 50 and older who experienced a stroke as the cases. As controls, the researchers selected Floridian adults aged 50 or older who did not experience a stroke. To assess each participant’s exposure status, the researchers asked the participants to fill out a questionnaire in which the participants were asked to retrospectively report if they have had hypertension in the past. When is the measurement error in hypertension in case 1 differential? (max. 4 points)
